,new and useful Improvements in Type- \Vriting Machines, of which the following is a specification.

My" invention relates to tabulatingmechanism for typewriting machines and its general object is to provide improved mech anism of the character specified.

iWIo-re specifically stated the object of my present invention is to provide a reversible tabulating mechanism which. may be employed in the usual way for advancing the carriage to predetermined points in its left-- ward travel and is also adaptable for tabulating in the opposite direction whenever tahulating of this character commonly called reverse tabulating is more suited to the work in hand.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and'particu- ,larly pointed out in the claims.

In carrying out my invention in the present instance I have applied it to a No.11 -lzitemington typewriting machine, and to.the

enominational tabulating mechanism com} monly employed with 1 said machine, .al-

though it is to be understood that said invention may be applied readily to other styles of writing" machines arid to other constructions oi" tabulating mechanism, denominational o1', otl 1e1-u-'ise.,' In the regular tabulato r of the Remington machine, and indeed in most denominational tabu'lators,

each-;-tabulator. key is adapted to project a denominational stop into the path of the 'colnmnstops and also .to' operate the release mecha ism, releasing the carriage and perg" mittingsit to be drawn leftward under the 45' pullofthe carriage-motor until arrested by the tic-acting stops at a predetermined point.

lathe present instance the releasing mechanisr'n an actuating link which connects a universalrock'fsh'aft, operative by-theitabulator key connections, with areleasing leverprovided with ja pinion for releasing the carriage feedrack. -I provide meanscomprising a train .of mechanism under the control of. key or finger piece for at will shifting,the link so as to break the connection between said rock shaft and said releasing lever and render the releasing mechanism ineffective when the tabulator keys are actuated. The result willbe that a tabulator key may at this time be actuated to project its stop without afiecting the carriage is a side elevation, partly in section, of a' No. 11 Remington typewriting machine embodying my invention, parts of the machine which are not necessary to an understanding of said invention being omitted. .Fig. 2 is a skeletonized side elevation of the'carriag'e releasing devices and switching mechanism shown in a different relationship from that illustrated in Fig. 1. Fig. 3 is a perspective viewof the-switching mechanism and carriage releasing devices. is a fragmentaryfront elevation showing the construction and mounting of the finger piece or key of the switching mechanism.

chine comprising a base 1, posts 2 uid a top plate 3 supports fixed track-ways 4 which through anti-friction balls 5 support a car-- riage 6 on which ismounted a platen 7. Co- 1 operative with the front face of the platenare type bars 8 each mounted on a stationary hanger 9 and connected through a train of devices comprising a link 10, lever 11 and a' second link 12 with a key lever 13, the key levers being t'ulcrumed on a stationary bar 14 and being each providedwitha restoring s'pring-15. A releasable teed racklG is se- "cured to arms 17 fulcrumed at 18 on ears 19 fixed to the rear of the carriage. Said feed rack normally meshes with a feed pinion 20 operatively connected with a pair of 'toothed escapement wheels 21 with which ooiifieretes a dog 22 mounted on a dog 'roo or 23 connected by a link'tll with a crank' arm 25' extending rearward from Fig. 4-

c .As shown in Fig. l the frame of the ma about the middle of a rock shaft 26. Near its ends the rock shaft is provided with rearwardly extending crank arms 27 from which depend arms or links28 supporting a universal bar 29 which underlies the key levers 13 and is operative thereby to actuate the dog 22 and operate the escapement devices to permit step-by-step letter feed movements of the carriage under the pull of a motor or spring drum 30 which is connected by 'a 1 strap 31 with anarm 32 fixed to the car riage.

Theparts thus far described are common to the No. 11 Remington machine. The tab; ulating mechanism usually employed in con-' nection with said Remington machine comprises a toothedstop bar 33 mounted on arms 34: fixed to and extending rearward from'the carriage, said bar being adapted to receive adjustable tabulator or column stops 35 with which cooperate a set of denominational stop levers -36 pivoted at 37 on a frame 38 secured to the main frame of the machine. The lower ends of said -le-' vers 36 are each provided with a key connection comprising a push rod39 having at its front end a tabulator key 40 operative to project the stop proper at the upper end of the associate lever 36 forward into the path of the column stops 35 Restoring springs 41 restore the stop levers and their key connections when released to normal position. The tabulator keys are adapted also to actuate carriage release devices comprising a bail li having a stationary pivot 43. Secured to the cross bar of the bail is a slotted release bar 44 which is operative by col- 'lars 45 fixed to the push rods 39. to swing the bail rearward and cause links 46 connected thereto to actuate crank arms 47 dewhich is fixed an angular lever member 49 which is connected by an actuating link 50 with the releasing lever.

The train of releasing devices heretofore described is of ordinary construction but the releasing lever is somewhat different from that heretofore employed and has a different connection with the actuating link. The

50 releasing lever member provided in the present case and numbered 51, is as shown in Fig. 3, angular in shape and is supported by pivot screws on a stationary bracket 53. The forward portion or arm'- of said lever carries a releasing pinion 54; which underlics the releasable carriage feed-rack 16 and is normally disconnected therefrom as appears in Figs. 1 and 2 but is-adapted to be swung u 'iward. to engage said rack and lift it out of mesh with the feed pinion 20, thus releasing the carriage. The releasing actuations are communicated to the releasing lover Bl from the actuating link 50, the rear arm of said lever and the upper end of said nk being connected in a novel manner.

pending from'a universal rock shaft .48 to Said rear arm of the lever 51. is provided a with an angular -slot 55, said slot comprising a substantially horizontal portion and having a- ,vertically disposed portion or enlargement at the forward end of the hori zontal portion. The upper end of the link is bifurcated to embrace the lever 51 as clearly appearsdn'Fig. 3,. the bifurcations 50 being connected at their upper ends by across pin or actuating stud 56 which extends transversely through the. slot 55 and is adapted to actuate the lever 51 when-lo;

cated near the rear end of said slot as shown in Figs. 1 and 3. With the link and stud thus located an operation of one of the tabulator keys 40 will project the associate stop lever 36 and also cause the link 50 to pull down the stud 56, said stud acting against the lower side of the horizontalportion of the slot 55 and swinging the releasing lever on its pivots, thus causing the pinion 54: to release the carriage which will move left-- ward until arrested by the engagement of the proximate column stop with the projected stop lever. The tabulating operations thus performed are of the regular and o dinary character.

As has been stated it is desirable attimes to tabulate in the reverse direction, that is, to arrest the carriage. at predetermined points in its travel from left to right instead of from right to left as is usual. To provide for this reverse method of t-abulating I have devised key controlled switching mechanism which is settable at will to disconnect the releasing devices and throw them out of the operative control of the tabulator keys. The switching mechanism includes a switch member. or lever memberwhich comprises a sleeve or hollow shaft 57 rotatably mounted on the shank of a ver-' ticallydisposed bearing screw 58 which depends from the top plate and has its upper end 59 reduced and threaded into said top plate, a nut 60 being provided to secure said bearing screw adjustably in place. Fixed to the sleeve 5.7 near its upper end is a laterally and rearwardly extending crank arm 61 formed with a slot 62, the side walls whereof-loosely embrace the link 50. 1 A restoring sprin 63 secured to said crankarm 61 at one en '1 and having a-stationary anchorage at its opposite end tends to pull r the crank arm constantly forward. Near its lower end the sleeve 57 has secured to it an oppositely extending crank arm 64 which is connected by a forwardly extending link 65 with a pin or screw 66, projecting laterally from a second lever member 67 pivoted on afixed fulcrum device or screw 68. The for ward end of the link 65 is looped around the shank of the screw 66 and is confined between the head of said screw and a washer 69 arranged on said shank. The forward end of the lever or arm 67 is bent laterally rightward in front of the neighboringccrner post and is formed into a finger. riece or key 7 O by which the switch-in g' mechanism may be conveniently actuated. A combined indicating-and stop frame or plate 71 is de tachabl secured by screws-72 to the front post a oresaid. Said frame is angular in cross sectionto fit around the inner front corner of the post 2 and its front portion is provided with suitable indicating marks such as Tab and OE, while its side portion is provided with laterally extending sto pins or lugs 73 and.74 for cooperation wit 1 the arm or lever 67, the pivot screw 68 whereof isscrewed into said side portion. It will be observed that the'link 65 is connectedv to the lever 67 between its fulcrum 'stop through the train of-devices described with and the key or finger piece 70, and when the line of the link is below the fulcrum, as in Figs. 1, 3 and 4, 'the spring 63 which, acting through the lever member 57,

willma-intain t e arm 67 engaged with the -7 3. .Since the arm 67 is connected the crank arm 61' said crank. arm will thus a have a definite and predetermined location at this "time and its slot 62 will'serve to guidedthe link ments when actuating the lever 51 and will hold, said link in proper normal relationship with said. lever. .It will further be noted 4 that at this time the fingerpie'ce 70 is below the Tab mark on' the indicating plate and nearer to said mark than to the other or Off mark, thus visually indicating to the operator that the switch is out of operation if andthat the releasing devices are set for operation so that they will release the car- 'riage when the tabulator keys are operated.

\Vhen it is desired to switch the releasing devices out of the control of the tabulator keys the. key or finger piece 70 is swung upward operating through the link 65 to turn the crank arm 64 rearward and the crank arm 61 forward, said arm 61 in turn operating to swing or switch the link for-- ward from the Fig. 1 position to the posi tion shown in full lines in Fig. 2. In the the upward and rearward past the fulcrum.

upward swinging'movement ofthe "arm 67 forward end of the link 65 willswing point 68 and as soon as it crosses the dead center the spring 63 will tend to cause the arm .67 to continue its upward swing and when said arm is arrested by theupper stop 74 as shown in Fig.- 2, said sprin will tend to maintain the arm engaged with the stop, thus definitely locating the crank arm 61' i es and the link controlled thereby in a new po-.

. sition with the result that the'actuating stud 56 will be re-located at the forward end of theslot 55 and just abovethe vertically dis posed ,portionlthereofl The spring 63 as will thus be seen is double act1ng,:'tendi 1ig c1, 64, tendsco,nsta ntly to ull said link 65' rearward,

50 in 'its up and down moveat one time to maintain the arm 67 down .the actuating device or stud 5'6, at predetermined positions in relationship to the actuated member or l6V81"5 1. Of course, it is'to be understood that while the construction involving the arm or key lever 67 and the associate stops 73 and 74 is preferred yet these devices, together with the described indicating devices, may be dispensed may simply be guided at its forward end so that said rod may be pulled forward and,

ushed back to effect the shifting of the .with and the link or pusli-and-pull-rod '65 ink 50. Whensaid stud is located at'its forward or Fig."2 position'as last described it will normally act against the upper horizontally disposed wall of the slot to prevent the rear arm of the lever from swinging downward, theres'ult being that the releasin pinion 54. will be restrained from acci-'- dentally swinging upwardjinto engagement with the feed rack 16. This is a desirable feature of construction otherwise the lever would be .free to swing on its pivot,

somewhat the heavier. and the tendency of the pinion 54'is to remain down out-of mesh, still it might accidentally engage with the rack to obstruct or interfere'unnecessarily and though the forward arm of said lever is I with the movements of the carriage. With the parts switched as described it will be 1in-' derstood that the finger piece'70 is proximate to the upper indicating mark 'on the plate 71, thus indicating visually' that the releasing mechanism is Off or disconnected. At this time if a tabulator key be operated its associate stop lever will be projected asbefore and the key connections willoperate the rock shaft ,48 and link 50, mov.{

ing these parts to the dotted'line. positions shown in'Fig. 2. The downward movement of the link, however, at this t-ime will be ineffective to actuate the lever. 51 for the reafson that the stud. 56 willmove downward in the vertical portion of the slot 55 to the po'.

sition shown by dotted lines'in' said Fig; 2,, p

the parts being so proportioned and arranged that atthe end of 'the stroke the stud will not quite .have'reached the bottom of the slot. In other words, thestud has a lost motion connection with the lev'eu'rfil' at this i without-;--

time and will move up and do actuating it. '.,The.-only efi'e'ctfthen 'ofjan operation project'th'e as'ociate stop lever; and the bp- ,e'rator -holdinig'xsaidttabul'ateri key pressed 111 pushes the-caprmgeifrom left to right-1 1 t-is arrested by the engagementof theprox imatc column or carriage stop with the projected stop lever or frame stop. The tabulator key is then released, the carriage remaining in the arrested position by'reason of the co-act-ion of the escapement devices which remain constantly effective on said carriage during the reverse tabulating operation described. It will be apparentthat 1f the carriage at this time were not connected with its cscapement 'devices'it might move leftward one or more spaces if the operator should lessen the rightward pressure against it before fully releasing the actuated tabulator key; On the other hand, even if under such circumstances such key? were released properly the carriage might move a letter space rightward from the arrested Fosition, this movement being the resalt 0 ria e while'being pushed back was released or isconnectedfrom the escapement'devices.

This reverse mode of tabulating is convenient in listingoperations as after an arrest of the carriage as'has 'just beendescribed, the operator writes in the number or other item comprised in the'list, thus causing the carriage to space step-by step leftward and thereafter merely aetuates the proper tabulator key and-o crates theline spacing handlc ofthe mac ine to line space the sheet, concurrently pulling .the carriage toward the'right until it is again. arrested. Such arrest brings the carriage in-proper position for writing the next item in the list under the item previously written. Thus considerable time is saved, as by the usual mode of tabulating the operator would, after writing in one item, pull the carriage rightward to the limit of its movement and then actuate the tabulator key to project the -desiredstop and permit'the carriage to run toward the left until arrested. The carriage during such run would travel over again, but in the opposite direction, a considerable, part of the path which it had just followed in moving from leftv to right. This unnecessary repetition ofimovement is saved by the employment of the reverse tabulator as de' scribed. Of course, reverse tabulating is not suited to all styles of tahulating work, but as has been stated is quite useful in operations of a listing character or the like. \Vhcn it is desired to tabulate in the regular way it is only necessary to swing the key or finger piece downward from the Fig. 2 to the Fig. 1 position, this operation rendering the tabulator keys a ain effective to release the carriage. In other words, the

switching key is effective to throw the train of releasing devices into or out of the control 'of the tabulating mechanism at will.

- It will be observed that I have provided by my present invention a device simple iii character and which may be applied to ex isting styles of typewriting machineswithout greatly changing any of the parts and that said device extends the functions of the o'rd'nary'tabulating mechanism and the con seq ent usefulness thereof.
